How come
Dim str As String = 1 & vbNewLine & 2 & vbNewLine & 3
Dim s As String() = str.Split
For d As Integer = 0 To s.Count - 1
MsgBox(s(d))
Next
Turns out to be:
1
2
3
Instead of:
1
2
3

I am trying to split a data field in VB using the split function.
The data field has the following character strings"&|:"
which I need to base my split on.
Dim elements As String() = Regex.Split(dataField, "&|:")
field1 = elements(1)
field2 = elements(2)
The field1 and field2 still have a trailing "&|" chracters.How do I check if the field1 and field2 have these trailing characters? How do I delete them?PS - I have tried "&\|:" as the delimiters in the split function which did not work.
I am using a thread to call a process which is spliting a text file into various text file and folder using the system.io , now when calling the Textsplit() with thread on click of a button i am getting the error below , how to use thread and why this error occurs.

I'm making a card game and the first thing I'm doing for it is generating a random card. I used an array for the cards (can't think of a better way to assign a picturebox to a card picture other then a huge select case block). I'm trying to split the 2D array into two parts but it doesn't work.

i have a string array that i want to output to a text file. the array size is 10000. i fill the array starting from 0 with some strings. at the end, i only want to show the array from index 256 to the last array that is not empty (for eg. if the array is filled with data from 0 to 2000, i only want the text file to show the data from 256 to 2000 and ignore the remaining strings). Is there any function to do this?t i use is shown below
Dim myArray(10000) as string
Dim strArray As New System.IO.StreamWriter("c:List.txt")
strArray.WriteLine("{0,10}{1,30}", "Index", "Symbol")

Im trying to work out what the best way to match 2 strings together, but with a difference.
String1 = "dog cat bird chair book table"
String2 = "the dog chassed the cat around the chair"
No I know I can break string1 up by space character and check if each word appears in string 2, I would prefer to not have to do that.If there some sought of regex that would take a group of words and retrun how many of them matched ?

I'm also pulling info from the bios, disk drives, video, etc. What I've noticed, is although it runs fine on my pc, it may error out on some pcs since it is hardware dependent.I'm having trouble implementing a check to find if it exists before I convert to a string and add it to my overall string.

I basically want to remove multiple strings within a string.
What would be the fasted method of get a string list of all values within [] in a string of text? For example: [client_name], are you are doing today? My name is [my_name]. The list of strings would be:

I'm writing some information to an SQL database in my program and I am using parameters with the SqlCommand class, thinking that this would take care of things like this for me but unfortunately it has not.
What I am doing is this: I create an instance of a class which has several properties, one of these properties is a String and in some cases there is no value assigned to this property,I then write the value of these properties to an SQL table.
what I was expecting was that if the value of this string property had not been set and I tried to get the value of it then I would just get String.Empty but it is actually returning Nothing.then when the SqlCommand comes to try and pass this in as a parameter it throws an exception stating that an expected parameter is missing.
This is how the property is defined:[code...]
I have managed to work around this by changing it so that the backing field is set to String.Empty when the class is initialised but I've never had to do anything like this before as far as I recall, I just thought that any String that had not had a value set would be String.Empty rather than Nothing. Am I just going mad or does anyone else think this is odd?
If I do this for example, I do indeed see the messagebox alert:[code...]
Also, I dont have the same problem with properties in this class that are Integers - if they are not set then I just end up with a 0 being written to the SQL table, which is what I want the string property to do (just write an empty string to the database if the property has not been set).
I'm guessing that is because Integers and other Value types have a default value (is it ALL value types that have a default value or just some?), but I thought Strings were made to behave pretty much in the same way with String.
Can I do anything more or less with IDictionary? How do these two collections differ?

The error is Value of type '1-dimensional array of string' cannot be converted to 'String'.
[code] I putted it in a loop but if it haves to convert 2 times the same pieces of word sometimes but it only converts the word it reads twice and leaves the rest in byte format [code] is there anyone else who can write me a better code to use or correct this one

All those numbers always change. But they're in the same line always
Now I wanna get "99" which is at <td class="alL">99</td>
After countless hours of searching I have been unable to get this code to work. If anyone can provide we with an alternative. I know the easiest way is to use the Split() function but im trying to do an alternative method by identifying the spaces within the string and splitting them up.
I tried the search function, but to no avail.
Attached is the code.
CODE:
My.Settings.regLibCardNo = "10-0000"
I want it to increment
CODE:
ListBox1.Items.Add(aString.Replace(" ", vbCrLf))
aString is like this: Tom Gary Kevin Bob Jason and so on, just all in 1 line What i want to do it add them in a listbox as a list. Also the string could be 1 name, 2 names or 200 names.I tryed replacing the " " with vbCrLf but since its a listbox all it does is remove the " "?
